Abstract: An enclosed two-part computer controlled cyclical and sequential through-flow conveying, usage and metering System (200) is disclosed, for use in the electric vehicle motive power provision industries, for said two-part enclosed System to sequentially convey small-volume rechargeable Cell-Modules by sequential conveyor-means in a metered through-flow sequential conveying manner within said two-part System wherein the first part is a Stationary Part that includes a specially manufactured Cell-Module dispensing Bowser and a specially manufactured Cell-Module Charging-Bay and wherein the second part is a Movable Part that includes a specially manufactured or specially adapted Cell-Module powered electric Vehicle having a specially manufactured Cell-Module Chamber installed within. A Nozzle (3) and a Portal (4) respectively provide means for the Stationary Part and the Movable Part to exchange a choosable plurality of small-volume rechargeable Cell-Modules (100) and (500).

Abstract: Power generating apparatus comprising a deep liquid container having a deep liquid therein, an endless rotatable loop element at least in part in the deep liquid container, and configured to be rotated by a driver about a horizontal or substantially horizontal axis of rotation, and energy harvester associated with the rotatable loop element. The rotatable loop element comprises at least one vessel including at least one variable-shape fluid-tight gas chamber and movable separator defining at least in part the gas chamber. The in use movable separator being at least partially movable in response to a change in hydropressure and the in use energy harvester harvesting energy as the movable separation means moves. The movable separator contracts or expands its captured gas volume in direct response to the changing external liquid pressures upon it as the vessel or descends.
